Subject: [PATCHv2 0/2] x86/mm: Make memremap(MEMREMAP_WB) map memory as encrypted by default
Make memremap(MEMREMAP_WB) produce encrypted/private mapping by default
unless MEMREMAP_DEC is specified.
It fixes crash on kexec in TDX guests if CONFIG_EISA is enabled.
v2:
- Fix sparse warning;
Kirill A. Shutemov (2):
memremap: Pass down MEMREMAP_* flags to arch_memremap_wb()
x86/mm: Make memremap(MEMREMAP_WB) map memory as encrypted by default
